Description

Technical Field

[0001] The present invention relates to the technical field of forest tree sowing, and particularly relates to an efficient sowing device for forest tree breeding. Background Art

[0002] Sowing is a key link in forest tree seedling cultivation, directly affecting the seed germination rate, the growth quality of seedlings and the later afforestation effect. When large-scale sowing of forest trees is carried out, professional planting equipment is generally used for sowing treatment. In actual planting, according to different soil conditions, the sowing depth of forest trees also needs to be adjusted appropriately. At present, common planting equipment directly scatters forest tree seeds into the opened sowing grooves, but the opening depth of the sowing grooves is a fixed value, which is difficult to adjust the depth according to the soil properties. Moreover, the surrounding soil may fall into the sowing grooves after they are opened, resulting in deviation in depth, affecting the sowing effect. In addition, after sowing, in order to ensure the normal growth of forest tree seeds, watering treatment is required, and the existing planting equipment cannot adaptively adjust the watering amount according to the sowing depth, resulting in the survival rate of forest trees planted at different depths being affected. Therefore, it is necessary to design an efficient sowing device for forest tree breeding. Summary of the Invention

[0036] Refer to Figure 1 - Figure 2 , a highly efficient sowing device for forest tree breeding, including a bottom plate 1. Two groups of symmetrically arranged mounting seats 2 are fixedly installed at the bottom of the bottom plate 1. A driving shaft 3 is rotatably installed on each group of mounting seats 2, and anti-slip wheels 4 are installed at both ends of the two driving shafts 3. The anti-slip wheels 4 are used to make the sowing machine travel more stably in the farmland. A protective cover 5 is fixedly installed on the bottom plate 1, and a handrail 6 is fixedly installed on the side wall of the protective cover 5. The protective cover 5 is used to protect the components on the bottom plate 1, and the handrail 6 is used to control the traveling direction of the sowing machine. The installation and connection method between the driving shaft 3 and the anti-slip wheel 4 adopts the connection method used in existing sowing machines. At the same time, components for controlling the gear and brake of the sowing machine can be arranged on the handrail 6, so that the sowing machine can normally perform sowing operations in the farmland.

[0037] Refer to Figure 1 - Figure 12 , a highly efficient sowing device for forest tree breeding, further includes a dual-purpose box 7. A storage cavity 8 and a water storage cavity 9 are opened in the dual-purpose box 7. A feeding seat and a water adding seat are fixedly installed on the protective cover 5. The feeding seat communicates with the storage cavity 8, and the water adding seat communicates with the water storage cavity 9. The storage cavity 8 is used for storing and processing the forest tree seeds for sowing, and the water storage cavity 9 is used for storing water and providing water source for watering the seeds after sowing. The storage cavity 8 and the water storage cavity 9 do not communicate with each other.

[0038] A separation hopper 13 is fixedly installed at the bottom of the dual-purpose box 7, and a plurality of conveying pipes 14 are fixedly connected to the bottom of the separation hopper 13. The cross-section of the separation hopper 13 is funnel-shaped, which is used to concentrate the forest tree seeds falling from the storage cavity 8, facilitating their smoother fall from the conveying pipes 14. A blanking assembly is installed on the separation hopper 13 and is matched with the plurality of conveying pipes 14. The blanking assembly is used to control the fall of the forest tree seeds in the storage cavity 8. The blanking assembly is composed of an arc-shaped blanking plate 46, a rotating shaft 24, and a blanking rod 25.

[0039] The arc-shaped blanking plate 46 is fixedly installed in the separation hopper 13. A plurality of discharge holes are evenly arranged in the middle of the arc-shaped blanking plate 46, and each discharge hole corresponds to the corresponding conveying pipe 14 in the up and down positions. When the forest tree seeds fall from the storage cavity 8 onto the arc-shaped blanking plate 46, they will pass through the discharge holes and fall from the conveying pipes 14, realizing precise positioning sowing treatment. The rotating shaft 24 is rotatably installed on the separation hopper 13 in a sealed manner. The blanking rod 25 is fixedly installed on the rotating shaft 24, and the blanking rod 25 is located at the bottom of the arc-shaped blanking plate 46. A plurality of blanking holes 26 corresponding to the positions of the corresponding conveying pipes 14 are arranged on the blanking rod 25. The design of the blanking rod 25 is used to control the relative opening and closing relationship between the discharge holes and the conveying pipes 14. When the blanking holes 26 on the blanking rod 25 are aligned with the discharge holes and the conveying pipes 14, the forest tree seeds can smoothly pass through the arc-shaped blanking plate 46 and fall from the conveying pipes 14. When the blanking rod 25 rotates to make the blanking holes 26 staggered with the discharge holes and the conveying pipes 14, the forest tree seeds will not enter the conveying pipes 14 through the blanking holes 26.

[0040] A depth adjustment assembly is installed on the bottom plate 1. The depth adjustment assembly is used to adjust the sowing depth. The depth adjustment assembly includes a connecting plate 18 slidably installed on the bottom plate 1, and a plurality of sowing pipes 23 are installed on the connecting plate 18 through a lifting mechanism. Each sowing pipe 23 is respectively matched with the corresponding conveying pipe 14. A through groove for the up and down sliding fit with the connecting plate 18 is opened on the bottom plate 1, and two sliding grooves are opened on the side wall of the through groove. Sliding blocks are slidably installed on both sliding grooves, and both sliding blocks are fixedly connected to the connecting plate 18. A lifting screw rod 22 is rotatably installed on the bottom plate 1, and the lifting screw rod 22 is threadedly connected to one of the sliding blocks. By rotating the lifting screw rod 22, the sliding block can drive the connecting plate 18 to move up and down in the through groove, and further the sowing pipes 23 can move up and down relative to the bottom plate 1 at the same time. Since the conveying pipes 14 are inserted into the sowing pipes 23 and the sowing pipes 23 are located at the lower end of the conveying pipes 14, the forest tree seeds falling from the conveying pipes 14 will fall from the bottom of the sowing pipes 23. Then it can be considered that the bottom of the sowing pipes 23 is the final sowing depth of the forest tree seeds. Therefore, by adjusting the initial height of the sowing pipes 23 relative to the bottom plate 1, the subsequent control of the sowing depth can be realized, thus completing the sowing operation of forest tree seeds at different depths.

[0041] The lifting mechanism is composed of a mounting frame 21, a fixed block 27, a reciprocating lead screw 28, a T-shaped rod, a T-shaped groove, a spring, and a driven bevel gear 29. The fixed block 27 is fixedly installed on the side wall of the connecting plate 18. The reciprocating lead screw 28 is rotatably installed on the fixed block 27, and the reciprocating lead screw 28 is threadedly connected to the mounting frame 21. The mounting frame 21 is fixedly connected to a plurality of sowing pipes 23. The T-shaped groove is opened at the top of the reciprocating lead screw 28. The T-shaped rod is slidably installed in the T-shaped groove. The spring is installed between the T-shaped rod and the T-shaped groove. The driven bevel gear 29 is fixedly installed on the top of the T-shaped rod. A driving bevel gear 30 meshing with the driven bevel gear 29 is fixedly installed on the rotating shaft 24. When the rotating shaft 24 rotates, it controls the sowing and dropping of forest tree seeds. At the same time, it drives the driving bevel gear 30 to rotate. Under the cooperation of the driving bevel gear 30 and the driven bevel gear 29, the rotation of the rotating shaft 24 drives the reciprocating lead screw 28 to rotate simultaneously, so that the sowing pipes 23 are inserted into the soil at the corresponding depth, completing the sowing process at the specified depth. Since the initial height of the connecting plate 18 needs to be adjusted by rotating the lifting lead screw 22 before starting sowing, the distance between the fixed block 27 and the separation hopper 13 also changes after adjustment. At this time, under the cooperation of the spring, the T-shaped rod, and the T-shaped groove, the height of the driven bevel gear 29 relative to the reciprocating lead screw 28 can change simultaneously with the position change of the connecting plate 18, ensuring the meshing effect between the driven bevel gear 29 and the driving bevel gear 30, so as to ensure that the up-and-down reciprocating movement of the sowing pipes 23 can be automatically controlled during the sowing process.

[0042] The impurity removal part is used to clean forest tree seeds during the sowing process. The impurity removal part includes a rotating cylinder 20 rotatably installed in the storage cavity 8. A round rod 19 is fixedly installed on the side wall of the cylinder 20. A collection box 11 communicating with the storage cavity 8 is fixedly installed on the side wall of the dual-purpose box 7. A negative pressure extractor 12 is fixedly installed on the top of the collection box 11. An arc-shaped guide plate is fixedly installed in the storage cavity 8 and is located at the bottom of the cylinder 20. A positioning groove is provided on the side wall of the cylinder 20. The cylinder 20 is hollow. When the positioning groove corresponds to the feeding seat, forest tree seeds can be put into the cylinder 20. The cylinder 20 is in contact with the top wall and the left and right side walls of the storage cavity 8. After the forest tree seeds are put into the cylinder 20, the rotation of the cylinder 20 can stir the forest tree seeds to a certain extent. And when the rotation of the cylinder 20 makes the positioning groove at the lower end, some of the forest tree seeds in the cylinder 20 can fall. At this time, with the cooperation of the arc-shaped guide plate, the falling position of the falling forest tree seeds can be guided so that they fall from the end close to the collection box 11. If it is necessary to screen and remove dust from the forest tree seeds, the negative pressure extractor 12 can be turned on, so that negative pressure is generated at the collection box 11 to extract shriveled seeds and collect dust. By controlling the magnitude of the negative pressure, the collection box 11 can extract and collect objects within a certain weight range. The negative pressure extractor 12 is an existing product, and its working principle and specific structure will not be elaborated here. A dust discharge groove can be opened at the bottom of the collection box 11, and a sealing plate is clamped on the dust discharge groove. After the impurity removal is completed, the sealing plate can be opened to uniformly clean the shriveled seeds and dust collected in the collection box 11.

[0043] The watering part is used to perform watering treatment with a corresponding capacity according to the sowing depth during the sowing process. The watering part includes a plurality of drain pipes 37 fixedly connected to the side wall of the corresponding sowing pipe 23. A drain groove 32 is opened at the bottom of the water storage cavity 9, and the bottom of the drain groove 32 communicates with each of the plurality of drain pipes 37. With the cooperation of the drain groove 32 and the plurality of drain pipes 37, when watering, the water in the water storage cavity 9 can be diverted into the sowing pipe 23, so as to perform precise watering treatment on the sown seeds. A control opening and closing component matched with the drain groove 32 is installed on the dual-purpose box 7. The control opening and closing component is used to control the opening and closing and the flow rate of the drain groove 32. The control opening and closing component is composed of a drain rod 33, a sealing ring 34, a plurality of drain holes 35 and a plurality of alignment holes 36. The sealing ring 34 is rotatably installed in the drain groove 32 in a sealed manner. The drain rod 33 is rotatably installed in the sealing ring 34 in a sealed manner. The plurality of drain holes 35 are all opened on the drain rod 33, and each drain rod 33 is respectively located at the upper end of the corresponding drain pipe 37. The plurality of alignment holes 36 are all opened on the sealing ring 34, and each alignment hole 36 corresponds to the position of the corresponding drain hole 35. When the drain hole 35, the alignment hole 36 and the drain groove 32 are on the same straight line, the water in the water storage cavity 9 can be discharged through the drain pipe 37, and when the three are not on the same straight line, the water in the water storage cavity 9 cannot be discharged.

[0044] A telescopic groove is opened on the side wall of the drain rod 33, and a telescopic rod 39 is slidably installed in the telescopic groove. The telescopic rod 39 is slidably and sealingly connected to the sealing ring 34, and a clamping plate 41 is fixedly installed at the end of the telescopic rod 39 located outside the sealing ring 34. A tension spring 40 is installed between the telescopic rod 39 and the telescopic groove. Under the elastic force of the tension spring 40, the clamping plate 41 can be closely attached to the sealing ring 34. At this time, it is considered that the sealing ring 34 and the drain rod 33 are in a fixed state. When the sealing ring 34 rotates, it can stably drive the drain rod 33 to rotate, so as to Figure 10 Taking the right view direction as an example, the diameter of the alignment hole 36 decreases in the clockwise direction. When it is necessary to control the single drainage volume, the clamping plate 41 is pulled outwards to separate it from the sealing ring 34, and then the drain rod 33 is rotated in the sealing ring 34 by rotating the clamping plate 41 to adjust the relative position of the drain hole 35 and the alignment hole 36, so as to control the actual drainage opening size. At this time, every time the sealing ring 34 rotates 180°, a certain corresponding amount of water will be drained, realizing watering treatment with corresponding flow rates for forest tree seeds sown at different depths, and meeting the normal growth requirements of forest tree seeds.

[0045] A double-shaft motor 15 is fixedly installed on the bottom plate 1. A rotating rod 10 is rotatably installed on the side wall of the dual-purpose box 7. One end of the rotating rod 10 and the double-shaft motor 15 are equipped with a belt drive structure one 16. Connecting gears 17 are fixedly installed at one end of the round rod 19 and on the rotating rod 10 respectively, and the two connecting gears 17 are meshed with each other. With the cooperation of the belt drive structure one 16 and the two connecting gears 17, the work of the double-shaft motor 15 can drive the round rod 19 to rotate in the opposite direction simultaneously, realizing the blanking process of forest tree seeds in the rotating drum 20;

[0046] A belt drive structure two 31 is installed between the rotating rod 10 and the rotating shaft 24. With the design of the belt drive structure two 31, the rotation of the rotating rod 10 can drive the blanking rod 25 to rotate in the same direction simultaneously, thus realizing the precise blanking of forest tree seeds. A belt drive structure three 38 is installed between the end of the round rod 19 far away from the rotating rod 10 and the end of the sealing ring 34 far away from the clamping plate 41. With the design of the belt drive structure three 38, the rotation of the rotating drum 20 can drive the sealing ring 34 to rotate simultaneously, realizing the watering process during sowing. A water guiding cavity 47 is opened in the sowing pipe 23, and the water guiding cavity 47 communicates with the drain pipe 37. Two water outlet holes 48 communicating with the water guiding cavity 47 are arranged at the bottom of the sowing pipe 23. Through the cooperation of the water guiding cavity 47 and the water outlet holes 48, water can be prevented from flowing inside the sowing pipe 23. Therefore, the problem that forest tree seeds adhere to the inner wall of the sowing pipe 23 and cannot be discharged due to the presence of water can be avoided. At the same time, referring to Figure 4 As shown, the right side surface of the sowing pipe 23 near the drain pipe 37 is inclined, and the bottom of the sowing pipe 23 is closed. Therefore, the forest tree seeds falling from the sowing pipe 23 fall from the right side surface of the sowing pipe 23 to complete sowing, while the water falls from the bottom of the sowing pipe 23. Therefore, the problem that forest tree seeds adhere to the inside of the sowing pipe 23 and cannot be discharged due to the presence of water can be effectively avoided.

[0047] A connecting shaft 42 is rotatably installed inside the protective cover 5, and a belt drive structure four 45 is installed between the connecting shaft 42 and one of the drive shafts 3. A fixed gear 44 is fixedly installed on the connecting shaft 42. One end of the dual-axis motor 15 away from the belt drive structure one 16 is fixedly installed with an incomplete gear 43 that cooperates with the fixed gear 44, and there are two tooth missing parts symmetrically arranged on the incomplete gear 43. Through the cooperation of the fixed gear 44, the incomplete gear 43 and the belt drive structure four 45, the seeder can be intermittently driven to travel when the dual-axis motor 15 rotates. The design of the two tooth missing parts on the incomplete gear 43 makes the connecting shaft 42 stay still twice during one rotation of the driving end of the dual-axis motor 15. While the rotating rod 10 always rotates when the dual-axis motor 15 works, and sowing and watering treatments are carried out once when the rotating rod 10 rotates 180°. Therefore, by setting the two tooth missing parts on the incomplete gear 43 to be symmetric in position, sowing and watering treatments can be completed when the seeder is in a stationary state, avoiding the problem of position deviation caused by sowing and watering during driving.

[0048] Set the included angle of the tooth missing part on the incomplete gear 43 to 30°, and control the transmission ratio of the driving bevel gear 30 and the driven bevel gear 29, so that when the rotating shaft 24 rotates 180°, the reciprocating lead screw 28 can be driven to rotate a corresponding number of turns to make the mounting bracket 21 perform a up and down reset movement once (the specific number of turns is determined by the number of turns of the reciprocating lead screw 28 driving the mounting bracket 21 to move up and down and reset). The adjustment method of the transmission ratio is the prior art. Under the above design, combined with Figure 6 - Figure 8 As shown, when the dual-axis motor 15 works and drives the rotating shaft 24 to rotate 180°, when the material dropping hole 26, the discharge hole and the conveying pipe 14 are in the same straight line, the drainage groove 32, the drainage hole 35 and the alignment hole 36 are also in the same straight line. At this time, sowing and drainage are carried out simultaneously. At the same time, the incomplete gear 43 is separated from the fixed gear 44, and at this time the reciprocating lead screw 28 makes the sowing pipe 23 at the lowest point. Then, when the dual-axis motor 15 continues to work and the rotating shaft 24 rotates 30°, the seeder remains stationary. At this time, the reciprocating lead screw 28 can move the sowing pipe 23 up a certain distance, and the conveying pipe 14 and the drain pipe 37 are both in a closed state. Then, the dual-axis motor 15 continues to work to make the seeder move forward, and when the rotating shaft 24 continues to rotate 60°, the reciprocating lead screw 28 makes the sowing pipe 23 at the highest position. Repeating the above operations can make the seeder automatically and orderly complete sowing at the corresponding depth and watering treatment with the corresponding discharge.

[0049] The belt drive structure 16, the belt drive structure 31, the belt drive structure 38, and the belt drive structure 45 are all prior arts, and their transmission ratios on this seeder are all 1:1. The dual-axis motor 15 is a prior product, and its working principle and specific structure will not be elaborated here.
